I'm insulating a 500sq ft. cabin in Southern Vt. and looking for a good wood stove to keep me toasty through the winter. I'd prefer something that will make it through the night, but I most things I find (the Jotul 203, Vt. Castings Intrepid II) that are small enough only burn for 5-6 hours. Any advice on what might work best would be much appreciated!
